DETAILED DESCRIPTION

[0021] The present invention is further described below in conjunction with specific embodiments. It should also be noted that, unless otherwise clearly specified and limited, terms such as: setting, installing, connecting, and connecting should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] A convenient atmospheric particulate matter content detection and analysis device, such as Figure 1 and Figure 2 As shown, it includes a placement frame 1, a support frame 2, a guide rod 3, a movable frame 4, a connecting rod 5, a first screw rod 6, a first rotating frame 7, a detector 8 and a fixing mechanism 9. The outer side of the placement frame 1 is rotatably connected to three support frames 2, the upper middle side of the placement frame 1 is connected to the first screw rod 6 by a thread, the upper side of the first screw rod 6 is rotatably connected to the first rotating frame 7, the upper part of the first rotating frame 7 is rotatably connected to the detector 8, a fixing mechanism 9 is provided on the first rotating frame 7, the lower middle side of the placement frame 1 is connected to the guide rod 3, the movable frame 4 is slidably connected to the guide rod 3, the movable frame 4 is rotatably connected to three connecting rods 5, and the connecting rods 5 are all rotatably connected to the adjacent support frames 2.

[0023] like Figure 1 , Figure 3 and Figure 4As shown, the fixing mechanism 9 includes a connecting frame 91, a first limiting frame 92, a first telescopic spring 93, a second rotating frame 94, a sliding frame 95, a second screw 96 and a clamping plate 97. The left and right sides of the lower part of the first rotating frame 7 are connected to the connecting frame 91, and the first limiting frame 92 is slidably connected to the connecting frame 91. The front and rear parts of the first limiting frame 92 are connected to the connected connecting frame 91 with a first telescopic spring 93. The second rotating frame 94 is rotatably connected to the side of the connecting frame 91 away from each other. The lower side of the second rotating frame 94 is provided with a card groove for easy fixation. The second rotating frame 94 is in contact with the adjacent first limiting frame 92. The upper part of the second rotating frame 94 is slidably connected to the sliding frame 95. The upper part of the sliding frame 95 is threadedly connected to the second screw 96. The upper side of the second screw 96 is provided with a handle for easy rotation. The lower side of the second screw 96 is rotatably connected to the clamping plate 97.

[0024] When using the utility model, firstly, the support frame 2 is opened and placed on the ground in the detection area, so that the support frame 2 supports the placement frame 1. When the support frame 2 is opened, the mobile frame 4 slides on the guide rod 3, driving the connecting rod 5 to rotate, thereby enhancing the stability of the support frame 2. After placement, the first rotating frame 7 is installed on the placement frame 1 through the first screw 6, and then the angle of the detector 8 is adjusted by rotating so that the detector 8 can detect and analyze the atmospheric particulate matter content in the area. When it is necessary to install the first rotating frame 7 on the mobile platform to detect the atmospheric particulate matter content, the first rotating frame 7 can be removed from the placement frame 1, and then the first rotating frame 7 can be placed on the mobile platform, and the connecting frame 91 can be rotated to adjust the angle of the detector 8. The second rotating frame 94 is moved to a horizontal state, so that the second rotating frame 94 squeezes the first limiting frame 92, and the first telescopic spring 93 is squeezed and contracted. After the second rotating frame 94 is in a horizontal state, the first telescopic spring 93 rebounds, so that the first limiting frame 92 is engaged with the slot in the second rotating frame 94 to fix the second rotating frame 94. Then, the length of the sliding frame 95 is adjusted, and the second screw rod 96 is rotated by the handle to move the clamping plate 97, so that the mobile platform is clamped between the clamping plate 97 and the sliding frame 95, and then the first rotating frame 7 is fixed on the mobile platform, thereby adapting to different usage scenarios and meeting different atmospheric particulate matter content detection requirements.

[0025] like Figure 1 , Figure 5 and Figure 6 As shown, it also includes a limiting mechanism 10, which includes a guide frame 101, a second limiting frame 102 and a second telescopic spring 103. The middle part of the second rotating frame 94 is connected to the guide frame 101, and the front and rear parts of the guide frame 101 are slidably connected to the second limiting frame 102. The second limiting frame 102 is snap-fitted with the adjacent sliding frame 95, and the second telescopic spring 103 is connected between the second limiting frame 102 and the connected guide frame 101.

[0026] By using the limiting mechanism 10 of the present device, the length of the sliding frame 95 can be limited. When the length of the sliding frame 95 needs to be adjusted, the second limiting frame 102 is pulled to move away from the sliding frame 95, and the second telescopic spring 103 is squeezed and contracted. After the length of the sliding frame 95 is adjusted, the second limiting frame 102 is released to make the second telescopic spring 103 rebound, so that the second limiting frame 102 and the sliding frame 95 are re-engaged, thereby fixing the sliding frame 95 and preventing the sliding frame 95 from moving.

Personnel familiar with the art can make various modifications or changes to the above embodiments without departing from the utility model concept of the present invention. Therefore, the protection scope of the present invention is not limited to the above embodiments, but should be the maximum scope of the innovative features mentioned in the claims.
